BOX-STRAPiING DEVICE.

Specification of LettersPatent.

the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which 1t appertains to make and use the same.

This invention relates to tensioningwire,

cord, or the like, and particularly relates to a box banding tool. 1 It is one of the ob-\ jects of the present invention to provide a simple, substantially constructed, durable, easily operable and practicable device for facilitating the banding of boxesor the like by drawing about the same a band of wire. It is one of the objects of the present in ven=tion to provide a device of this type in which the parts are simple and inexpensive, and which may be rapidly and accurately adjusted and box. Another object ,of the invention is to provide asimple means for opening and closing a set of gripping aws; to provide.

means for holding the relatively movable elements o f the device temporarily 'in any given position; and further to provide operated in the banding of a means for preventing the clogging or j am-' ming of the device because of the banding element or wire becoming caught between the elements of the tool in such positions that would render the tool clogged.

With the above and other objects in view as will be rendered manifest to those skilled in the art, the invention consists of the construction, the combination, and in details and arrangements of the parts as more particularly hereinafter set forth relative to the embodiment of the invention illustrated in the accompanying drawing, in which Figure 1 is a perspective view of the device in application, and Fig. 2 is a cross section ust above the top of the slide.

The tool comprises a main jack member or beam 2 at the upper end of which is provided a suitable purchase member 3, and at its lower end is formed to normally engage a rest or support or portion of a box, for instance, to be bound and grapple a piece of wire W, which is provided with an eye resting agalnst the bifurcated point 4 of the beam 2, While the stretch or band of through the beam Patented'Mar. 11, 1919.

wire is thence led around the box to be boundand forwardly and upwardly through the eye and into a position between a pair of jaws or grippinglmeans on the beam. In

this case the grip-ping means comprises a pair of toothed aWs 55 set on pivots 66 the faces of the jaws being opposed to each other So that when moved downwardly on their pivots they will embrace the interposedstretch of wire. To secure the automatic closing of the jaws on the wire they are each provided with an outwardly extending lever arm .7 to the ends of which it attached a link or rod 8, the upper end of each rod being connected at 9 to a handle or lever 10 of suitable construction which is pivoted at 11 on a part of or on the beam 2. The fulcrum or pivot 11 of the operating lever 10 is shown on one side of the beamsacross which the lever extends transversely, the pivoting point 9 of the connecting rod being disposed between the pivot 11 of the lever and its swinging end.v The gripping means or jaws have their pivots Gmounted on a side face of a slide 12 shown 'as encompassing the body of the beam 2 and in operation when the lever 10 tion along the beam 2, a suitable means may be employed here illustrated as comprising a brake spring .13 interposed between one element of the slide 12 and the adjacent body of the beam 2.

In order to prevent the wire whlch is to be tensioned from jamming or clogging by becoming caught between the faces of the jaws 5-5 and the adjacent side of the slide 12, the latter is provided with a transversely projecting lug 14 in the meeting plane of the jaws 55, this preventing the wire from being pushed so close to the face orside of the slide 12 that it could pass between-the slide and the jaws.

What is claimed is:

1. A box banding tool comprising a beam having one end notched and adapted to bear upon a box element and straddle a wire having' aneye in its end; a lever pivoted on the beam; a slide mounted on the beam between the lever and the beam point; gripping aws on the slide; and link connections between the jaws and the lever whereby the jaws are opened and closed by the lever to draw a part of the wire through said eye.

2. A box banding tool comprising a beam having one end adapted to bear upon a box element and straddle a wire having an eye in its straddled end; a lever pivoted on the beam; a slide mounted on the beam between the lever and the beam point; grip ping jaws on the slide to bite upon a part of the looped wire passed through the eye and connections between the jaws and the lever whereby the jaws are opened and closed by the lever, the latter first closing the jaws and then bodily shifting the slide and jaws when moving away from the notched end of the beam and pulling the wire in the same direction that the lever moves.

8. A box banding tool comprising a beam having one end provided with a i-notch and adapted bear upon a box element and straddlea wire laid on said element; a lever pivoted on the beam; a slide mounted on the beam between the lever and the beam point; gripping jaws on the slide, connections between the jaws and the lever whereby the jaws are opened and closed by the lever, and brake means for holding the slide in difierent positions along the beam.

A. box banding tool comprising a beam having one end adapted to bear upon a box element and straddle a wire; a lever pivoted on the beam; a slide mounted on the beam between the lever and the beam point; gripping jaws on the slidepconneetions between the jaws and the lever whereby the jaws are opened and closed by the lever, and

means for frictionally holding the slide in F different positions along the beam.

5. A box banding tool comprising a beam having one end bifurcated and adapted to bear upon a box element and straddle a Wire; a lever pivoted on the beam; a slide mounted on the beam between the lever and the beam point; gripping jaws on the slide, connections between the jaws and the lever whereby the jaws are opened and closed by the lever, and means for holding the slide in different positions along the beam, said holding means comprising a spring brake reacting between the slide and beam.

6. A box banding tool comprising a beam having one end bifurcated and adapted to bear upon a box element and straddle a wire; a lever pivoted on the beam; a slide mounted on the beam between the lever and the beam point; gripping jaws on the slide; and connections between the jaws and the lever whereby the jaws are opened and closed by the lever the slide having means tor preventing the wire from becoming disposed between the sides of the jaws and the adjacent race of the slide.

In testimony whereof I aiiix my signature.
